Norse mythology for bedtime the last few days.
We're reading out of D'Aulaires Book of Norse Myths, which is fine, because D'Aulaire's is the awesome. However, when it comes to Ragnarok, they have to skimp just a little, because they want to stay true to the source material. And while Ragnarok is well attested, none of the sources are big on the details. Which has always struck me as a bit of a pity.
